New features including scriptable HUD images, a versus mode HUD with scripted sound and animation, improved versus camera tilt, improved support for more than one controller, controller settings live update, 'threat' poses when holding attack key, experimental 'multiple lives' damage model, and more!

That's brilliant! You've done so much work up to this point that all you needed to add was a HUD to the game and it's ready to play in that mode! Also, as a fan of Mario and Luigi: Bowser's inside story, I think the animation ques are a great touch.

I'm really into this fighting system. It's like samurai fighting, if you touch the other person, you win. That allows for fast paced combat and you need to master your defensive skills as much as your offensive.
